HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 715,621, dated December9, 1902.

Application filed July 21,1902. Serial No. 116,312. (No model.)

To all whom it may concern.-

Be it known thatI, JOSEPH STIFTER, J r., a citizen of the United Statesof America, residing at Pittsburg, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements inHose-Couplers, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to certain new and useful improvements inhose-couplers, and has for its object the provision of novel meanswhereby a hose may be rapidly'and firmly secured together. r

Another object of my invention is to provide a hose-couplerwherebyscrew-threads are dispensed with and provide'a coupling which will bewater-tight and easily secured together.

Another object of my invention is to provide a hose-coupler that will beextremely simple in construction, strong, durable, comparativelyinexpensive to manufacture, and highly efficient in its operation.

With the above and othervobjects in view the inventionconsists in thenovel construction, combination, and arrangement of parts, to behereinaftermore fully described, and specifically pointed out in theclaim.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, and whereinlike numeral of reference indicate like parts throughout the severalviews, in which- Figure 1 is a side elevation of one part of my improvedcoupler. Fig. 2 is a vertical section of the adjoining part. Fig. 3 is aside elevation of the parts secured together and locked.

In the drawings the reference-numeral 1 indicates the neck of myimproved coupler, to which the hose is secured in any suitable manner,and 2 represents. an enlarged flange formed integral with said neck,said flange being annular in shape and having flat sides 3, said sidesbeing extended down a desired distance, as indicated at 4.

The reference numeral 5 indicates the lower portion of the neck, whichcarries a rubber gasket -6, and formed integral with the portion die thedownwardly-extending portion 7.

Pivoted upon the flattened sides 3 is the lever 8, which carries thehook portion 9 and a handle 10. This handle is semicircular in form andhas formed integral with it a similarhook'and lever, as shown in Fig. 1,this similar portion being secured to the upper side of the coupler.

The reference-numeral 11 indicates the lower portion of thecorresponding coupler, I and upon this portion 11 is secured the hose.

The reference-numeral 12 indicates the upper portion of thecorresponding coupler,

which has its sides cut away, as indicated at 14, and has an annularinterior seat, as indicated at 15, forthe reception of the portion 5,carrying the rubber gasket 6 of the portion illustrated inFig. 1.

The reference-numeral 16 indicates an annular seat, which carries arubber gasket 17, and upon this gasket rests the portion 7, asillustrated in Fig. 1 of the drawings.

The reference-numeral 18 indicates a plate, which is secured upon theflattened side 19 of the portion 12 by means of screws 20, and thisplate has formed integral therewith a pin 21, which carries a head 22.

The operation of my improved hose-coupler is as follows: It beingdesired to secure the hose-coupler together, the parts 7, 5, and 2 areforced into the parts 12 and 11 until the annular flange 2 restswithinthe cut-away portions 14, when the handle 10 is thrown down andthe books 9 engage the pins 21, thereby locking the same.

While I have'shown the most practical embodiment of my invention,it willbe obvious that various changes maybe made in the details ofconstruction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a hose-coupler, the combination of the two sections thereof, one ofsaid sections being provided with a peripheral flange, said flange beingformed with curved extensions, the other section receiving the inner endof the first-named section, and having its inner end provided withcurved recesses, in which In testimony whereof I afii x my signature inthe presence of two Witnesses.

JOSEPH STIFTER, JR.

the curved extensions of the said flange are received, a pair of platesremovably secured to the last-mam ed section,headed studs formedintegral with the said plates, and levers car- I ried by the first-namedsection, said levers being provided with book portions to engage thesaid studs, substantially as described.
